A sprinter who weighs 670 $\mathrm{N}$ runs the first 7.0 $\mathrm{m}$ of a race in 1.6 $\mathrm{s}$ starting from rest and accelerating uniformly. What are the sprinter's (a) speed and (b) kinetic energy at the end of the 1.6 $\mathrm{s}$ ? (c) What average power does the sprinter generate during the 1.6 $\mathrm{s}$ interval?

Fundamentals of Physics

A 220-lb man jumps out a window into a fire net $36 \mathrm{ft}$ below. The net stretches $4.4 \mathrm{ft}$ before bringing him to rest and tossing him back into the air. What is the potential energy of the stretched net?

Physics

A 62-kg person jumps from a window to a fire net 20.0 m directly below, which stretches the net 1.4 m. Assume that the net behaves like a simple spring. ($a$) Calculate how much it would stretch if the same person were lying in it. ($b$) How much would it stretch if the person jumped from 38 m?

Physics: Principles with Applications

A person jumps from a fourth-story window 15.0 $\mathrm{m}$ above a firefighter's safety net. The survivor stretches the net 1.0 $\mathrm{m}$ before coming to rest, Fig. $2-37 .(a)$ What was the average deceleration experienced by the survivor when she was slowed to rest by the net? (b) What would you do to make it "safer" (that is, to generate a smaller deceleration): would you stiffen or loosen the net? Explain.
